The groundbreaking A2 is the MTB trail helmet from Troy Lee Designs that meets all criteria. Its stylish shell features not only large intake and exhaust vents but also provides the best impact protection. From removable visor screws and the innovative MIPS® system to an industry-first dual-density EPP + EPS liner that protects against both high and low-speed impacts; this is a helmet that takes your safety seriously. Add an adjustable strap and an X-Static® Pure Silver Comfort Liner, and comfort is on par with protection. The MIPS multi-directional impact protection system reduces rotational forces on the brain in certain accident scenarios. The industry's first dual-density EPP and EPS helmet inner shell offers top-notch protection against high and low-speed impacts. The 16% thicker EPP and EPS helmet inner shell at the front compared to the A1 increases protection in typical impact zones. Innovative removable visor screws reduce the likelihood of snagging in an accident. Large intake and exhaust vents ensure maximum cooling performance with over 25% higher airflow compared to the A1.
